What is Amfexa (Dexamfetamine)?
Amfexa is a prescription medication containing the active ingredient dexamfetamine sulfate. It belongs to a class of drugs known as central nervous system (CNS) stimulants or psychostimulants .Buy Amfexa Tablets (Dexamfetamine 20mg) online
How It Works
The mechanism of action of dexamfetamine is fascinating and somewhat counterintuitive. While it’s a stimulant, it produces calming and focusing effects in individuals with ADHD. Here’s how it works:Buy Amfexa Tablets (Dexamfetamine 20mg) online
Dexamfetamine increases the activity of two important neurotransmitters in the brain: noradrenaline and dopamine . These chemical messengers play crucial roles in:Buy Amfexa Tablets (Dexamfetamine 20mg) online
- Attention and concentration
- Impulse control
- Executive functions (planning, organizing, decision-making)
- Mood regulation
In people with ADHD, certain brain areas involved in concentration and impulse control are underactive. Dexamfetamine works by blocking the reuptake of noradrenaline and dopamine, allowing these chemicals to remain active between nerve cells for longer periods. It also mimics the action of these neurotransmitters . The result is improved communication between neurons in the brain regions responsible for attention and behavior control.Buy Amfexa Tablets (Dexamfetamine 20mg) online
